Description

Technical Field

[0001] The invention relates to an ultra-high voltage test container, in particular to an online testing system for injecting a cable into the ultra-high voltage test container. Background Art

[0002] Ultra-high pressure test vessels, in the testing work, there are more and more deep wells and high-pressure wells. In order to improve the success rate of high-pressure well testing and inspect the performance of testing tools, a real simulation of the downhole environment is needed; the ultra-high pressure normal temperature rapid testing system mainly simulates the high-pressure working environment of oil and gas wells, and can perform instrument performance testing and other tests. The ultra-high pressure test vessel is a carrier of extreme high-pressure environment and also belongs to special equipment. The test space of the test object is formed inside it. It is connected to the pipeline system through a pipeline interface, and the pressure inside the ultra-high pressure test vessel is raised and lowered through the flow of the medium. The ultra-high pressure pressurization system is connected to the ultra-high pressure test vessel through a pipeline, and it is responsible for providing the medium required for pressurization and decompression of the ultra-high pressure test vessel.

[0003] The upper sealing head of the ultra-high pressure test container is provided with a live detection sealing lead-in port, which is convenient for users to monitor instruments and equipment under pressure in real time; during the online test process, the cable needs to be injected. Due to the sealing extrusion friction resistance of the upper sealing head of the ultra-high pressure test container and the high-pressure environment inside the ultra-high pressure test container, the test cable is difficult to move downward only by its own weight, but if a driving structure is added, the sealing will be affected, that is, the existing technology cannot coordinate the sealing and cable injection well; for example, a high-pressure well test cable pressurized injection device in the prior art (Chinese patent, authorization announcement number CN107956446B) records that "the cable moves downhole under the clamping force of the active capsule and the liquid-filled capsule to achieve the injection of the test cable", but there will be a gap on both sides of the cable between the active capsule and the liquid-filled capsule; although an "O-ring sealing combination" is added on the top, the "O-ring sealing combination" will be tightly attached to the cable for sealing, which will form a certain resistance to the injection of the cable, causing a large pulling force to form on the cable from the "O-ring sealing combination" to the "active capsule"; that is, there is also a situation where the sealing and cable injection cannot be well coordinated; Therefore, an online testing system for cable injection into an ultra-high pressure test container is proposed to solve the above-mentioned problem that "the existing technology cannot well coordinate the sealing and cable injection conditions".

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] In the embodiment of the present invention, Figure 1 , Figure 2 , Figure 4 and Figure 6As shown: an online testing system for cable injection into an ultra-high pressure test container, comprising a cable drive assembly 200 installed inside a cable injection shell assembly 100, wherein the cable drive assembly 200 comprises a cable drive tube 500, wherein the cable drive tube 500 comprises an outer rotating cylinder 510 and an inner driving member 520 inserted and fixed inside the outer rotating cylinder 510, wherein the outer rotating cylinder 510 is used to receive the power outputted by the cable injection shell assembly 100 and transmit it to the inner driving member 520, thereby driving the inner driving member 520 to rotate; Continue reading Figure 7 , Figure 9-11 : The inner driving member 520 includes a sealing spiral plate 521 and a driving spiral plate 522. The sealing spiral plate 521 and the driving spiral plate 522 have the same spirality, and the sealing spiral plate 521 is spirally inserted in the spiral gap of the driving spiral plate 522; When the cable 600 enters the entrance of the end of the sealing spiral plate 521 and the driving spiral plate 522, the sealing spiral plate 521 and the driving spiral plate 522 will rotate with the outer rotating cylinder 510; in this process, the sealing spiral plate 521 and the driving spiral plate 522 will apply a main driving force 700 inclined downward to the cable 600 on the basis of sealing the cable 600, and the main driving force 700 is decomposed into a radial driving force 710 and a columnar driving force 720, and the columnar driving force 720 will push the cable 600 into the ultra-high pressure test container; It should be noted that the sealing spiral plate 521 has a rubber pad laid on the contact surface with the cable 600 to increase the sealing degree.

[0023] Therefore, in the process of online testing, it is necessary to inject the cable. Due to the sealing extrusion friction resistance of the upper sealing head of the ultra-high pressure test container and the high pressure environment inside the ultra-high pressure test container, it is difficult for the test cable to go down only by its own weight. However, if a driving structure is added, the sealing performance will be affected. That is, the existing technology cannot coordinate the sealing performance and the cable injection performance well. The present invention can achieve: The online test equipment enters the cable injection shell assembly 100 and the cable drive assembly 200 through the cable 600 and is injected into the ultra-high pressure test container for testing. During the test, the cable 600 enters the end entrances of the sealing spiral plate 521 and the driving spiral plate 522. The outer rotating cylinder 510 receives the power output by the cable injection shell assembly 100 and transmits it to the inner driving member 520, driving the inner driving member 520 to rotate; causing the sealing spiral plate 521 and the driving spiral plate 522 to rotate with the outer rotating cylinder 510; the rotating sealing spiral plate 521 and the driving spiral plate 522 will apply a main driving force 700 that is inclined downward to the cable 600. The main driving force 700 is decomposed into a radial driving force 710 and a columnar driving force 720. The columnar driving force 720 will push the cable 600 to be continuously and stably injected into the ultra-high pressure test container; at the same time, the sealing spiral plate 521 and the driving spiral plate 522 will fit on the cable 600 to perform a seal; based on the working principle of the sealed entry of the cable 600, desynchronization promotes the cable 600 to be continuously, efficiently and stably injected into the ultra-high pressure test container.

[0024] In the embodiment of the present invention, Fig.11 , Fig.12 and Fig.15 As shown: the driving spiral plate 522 has a plurality of unit driving blocks 523 laid on the contact surface with the cable 600 , and the plurality of unit driving blocks 523 are distributed in an array along the spiral body of the driving spiral plate 522 ; the unit driving blocks 523 include a supporting plate 5231 and an abutting plate 5232 .

[0025] In the embodiment of the present invention, Figure 12-Figure 15 As shown: the support plate 5231 is fixed on the spiral body of the spiral plate 522, and a gas injection cavity 52311 is opened on the support plate 5231; The abutment plate 5232 includes an abutment plate 52321, one end of which is rotatably assembled on the support plate 5231, and the other end of the abutment plate 52321 is rotatably assembled with a piston 52324, and the piston 52324 is movably inserted into the air injection cavity 52311; the air injection cavity 52311 is connected to the cable injection shell assembly 100 through a connecting hose.

[0026] Therefore, the rotating sealing spiral plate 521 and the driving spiral plate 522 will fit on the cable 600, and the cable injection shell assembly 100 is used to inject gas into the injection chamber 52311. When the gas pressure increases, it will push the piston 52324 outward, and the piston 52324 will push the abutment plate 52321 outward to rotate outward, so as to promote the abutment plate 52321 to fit more closely on the cable 600; the abutment plate 52321 is turned outward to form an inclined table surface, so as to make the inclined table surface fit on the cable 600 from the front, improve the stability of the force point, and push from the front; so as to accurately realize that the driving spiral plate 522 applies a main driving force 700 inclined downward to push the cable 600 to be continuously and stably injected into the interior of the ultra-high pressure test container.

[0027] In the embodiment of the present invention, Fig.14 and Fig.15 As shown: a positioning column 52322 is fixed at one end of the abutting plate 52321, a U-shaped fixing plate 52323 is rotatably mounted on the positioning column 52322, and the U-shaped fixing plate 52323 is fixed on the supporting plate 5231; A hinge chain 52326 is fixed to the other end of the abutment plate 52321 , a support column 52325 is fixed to the hinge chain 52326 , and the support column 52325 is fixed to the piston 52324 .

[0028] Regarding the "hinge chain 52326", it should be explained that: the hinge chain 52326 belongs to the prior art, for example, it can be composed of a U-shaped plate, a rotating plate and a limit column, and its detailed structure can be found in existing literature journals, and it can also be purchased directly on the market, or parts can be purchased on the market to assemble it, etc.; it is not what the present invention wants to protect, and will not be elaborated here.

[0029] In the embodiment of the present invention, Figure 7 and Figure 8 As shown: the outer rotating cylinder 510 includes an outer rotating cylinder body 5101, a sealing spiral plate 521 and a driving spiral plate 522 are inserted and fixed on the inner wall of the outer rotating cylinder body 5101, and a driving gear ring 5102 is fixed at one end of the outer rotating cylinder body 5101, and the driving gear ring 5102 is powered by the cable injection shell assembly 100; The outer rotating cylinder 5101 is rotatably equipped with an air guide ring 5103 at its other end, and an air guide cavity is opened inside the air guide ring 5103. The air guide cavity is one-way open and faces the outer wall of the outer rotating cylinder 5101; the air injection cavity 52311 is connected to the air guide cavity through a connecting hose 1, and the air guide cavity is connected to the cable injection shell assembly 100 through a connecting hose 2.

[0030] In the embodiment of the present invention, Figure 3 and Fig.16As shown, the cable injection shell assembly 100 includes a test container coordinator 300 , which includes an outer shell 310 and a test container coordinator 320 . The test container coordinator 320 is assembled inside the outer shell 310 .

[0031] In the embodiment of the present invention, Fig.16 and Fig.17 As shown: the test container cooperating member 320 includes two parallel chains 321, the chains 321 are movably placed inside the housing 310, and driven by a motor installed inside the housing 310 to rotate in a closed loop; the chains 321 are composed of a plurality of chain links 322; The test container cooperating member 320 further includes a plurality of clamping rings 326, which are evenly spaced along the chain 321, and the clamping rings 326 are assembled on a vertical plate 327, which is fixed on a horizontal plate, which is fixed on the chain 321; The test container cooperative part 320 also includes multiple arc-shaped sealing plates 325, which are distributed in a cross array with multiple clamping rings 326; the arc-shaped sealing plates 325 have an electric telescopic rod 323 fixed at their bottom, the electric telescopic rod 323 is fixed on the drag plate 324, and the drag plate 324 is fixed on the chain 321.

[0032] Regarding the "clamping ring 326", it should be explained that: the clamping ring 326 belongs to the prior art, for example, it can include two symmetrically distributed semicircular plates, both of which are provided with semicircular holes, and the two semicircular plates are connected by a hydraulic telescopic rod; the two semicircular plates are rotatably assembled on the vertical plate 327; its detailed structure can be found in existing literature journals, and it can also be purchased directly on the market, or parts can be purchased on the market to assemble it, etc.; it is not what the present invention wants to protect, and will not be elaborated here.

[0033] In the embodiment of the present invention, Figure 2 and Figure 4 As shown: the cable drive assembly 200 further includes a test container coordinated tube 400, and two cable drive tubes 500 are provided and distributed at the ends of both ends of the test container coordinated tube 400; The test container coordination tube 400 and the cable driving tube 500 are located on the same straight line and are interconnected.

[0034] Further, such as Figure 4 and Figure 5 As shown: the test container coordinated tube 400 includes a test container coordinated tube body 430, and the test container coordinated tube body 430 is respectively provided with a bearing ring 410 at the ends of both ends thereof, and the cable driving tube 500 is rotatably connected to the test container coordinated tube body 430 through the bearing ring 410; The test container cooperates with the tube body 430 to form an access groove 420 on its side.

[0035] Therefore, after the cable 600 enters the interior of the test container coordinated tube body 430, the motor is started to drive the chain 321, and the chain 321 drives the multiple clamping rings 326 to enter the interior of the test container coordinated tube body 430 through the access groove 420 in turn, and the chain 321 uses the multiple clamping rings 326 to clamp the cable 600 in turn, pushing the cable 600 forward and injecting it into the ultra-high pressure test container. After one end completes pushing the cable 600, the clamping ring 326 will follow the chain 321 back to the other end to continue clamping the cable 600; at the same time, the cable 600 between the multiple clamping rings 326 is clamped by the test container coordinated tube body 430, the two clamping rings 326 in turn. 26 and the arc-shaped sealing plate 325 are enclosed to form a closed space, and then the pressure environment of the closed space is changed through the pressure regulator installed in the shell 310 (the pressure regulator can be a pressure regulator, and the pressure regulator changes the pressure environment of the closed space by changing the amount of air in the closed space) to achieve the environmental conditions inside the ultra-high pressure test container; on the basis of promoting the continuous, efficient and stable injection of the cable 600 into the ultra-high pressure test container, the pressure environment of multiple unitized closed spaces is changed to synchronize the environmental conditions inside the ultra-high pressure test container; the sealing and the injection of the cable 600 are well coordinated to avoid the online test from affecting the ultra-high pressure test container.

[0036] Since the test container cooperative tube 400 is located between the two cable driving tubes 500, the cable 600 can be continuously injected into the ultra-high pressure test container, and high sealing can be achieved collaboratively while the cable 600 can be efficiently, continuously and stably injected.
